No wonder beginners give up.

From page 14 of Ines Scheurmann's "Aquarium Plants Manual," published by
Barron's, probably the most widely used reference book for beginners:

"High carbonate hardness by itself can also be lowered by CO2 fertilization
or peat filtration."

Is anyone going to help the poster with her algae? I recommend:

1. Reduce lighting to 11 hours and maintain lowered temperature.
2. Continue fertilizing with CO2 but limit introduction of additional
nutrients.
3. Forget the pH and kH - they are what they are.
4. Test again in a month and let us know what happened if you feel like it.

Regards, Snark

Adding CO2 does NOT change Alkalinity (which is _really_ what you are
talking about when you use the term "KH".
